Assignment 1-2D Meshing Challenge

ASSIGNMENT-1

AIM:

PROCEDURE:

PART-1

GEOMETRY CLEANUP

Import the part-1.hm file to hypermesh under radioss profile.
The component has more free edges and duplicate faces using quick edit to delete the duplicate surfaces. Toggle edges is used to stitch the free edges by increasing tolerance value. filter surfaces is used to fill the deleted surface.
surface edit is used to trim surfaces and later can be toggled . using wireframe mode we can check the geometry for free edges.

MID SURFACING

Mid surface using offset+planes+sleep, the surfaces are selected and mid surface is created.
fill the holes less than 5mm diameter using quick edits and suppress the lines using toggle edges.
toggle the unwanted features line that could fail for min length. Assign the property material.

MESHING

Set the mesh parameter and quality criteria, min length=3.5, max length=7mm.
Automesh the component with target element size 5mm
Quality index , clean up the element that fail.driag tria element , places nodes, element optimize are effectively used to clear quality element fails.

PART-2

GEOMETRY:

Import the part file to hypermesh under radious profile .
the component has more fre edges and duplicate face using quick edit to delete the duplicate surfaces. toggle edges is used to stitch the free edges by increasing tolerance value. filtersurface is used to fill the delete surface.
trim is used to trim the surfaces and later can be toggled . shift +f2 is used to clear all nodes
using wireframe mode we can check the geometry for free edges.

MID SURFACING :

Mid surfacing using offset +planes+sleep, the surface are selected and midsurface is creted.
filler surface is used to fill the holes and then use toggle edit command to suppress the lines . washer zone is created for holes.
Assign material and property.

MESHING:

Set the mesh parameter and quality criteria ,min length=3.5mm,max length=7mm.
Automesh the component with target element size 5mm
quality index, clean up that element that fail. driag tria element , places nodes, element optimize are effectively used to clear quality element fails.

PART-3

GEOMETRY:

Import the part file to hypermesh under radious profile.
The component has more free edges and duplicate faces. using quick edit to delete the duplicate surface. Toggle edge is used to switch the free edges by increasing tolerance values. filter surface is used to fill the deleted surface.
surface edit is used to trim the surface and later can be toggled. shift+f2 is used to clear all nodes.
using wireframe mode we can check the geometry for free edges.

MANUFACTURING:

Mid surfacing using offset+planes+sweep the surfaces are selected and mid surface is created.
filter surface is used to fill the holes less than 5mm and then use toggle edit command to suppress the lines.
Assign material property

MESHING:

Set the mesh parameter and quality criteria, min length=3.5mm, max length=7mm.
Automesh the component with target element size 5mm.
component is then reflected using tools<reflect and nodes and connected using replace nodes[f3].
element quality is checked for failiures using quality index and thickness is previewed using 2D detailed representation.
